SPECIFICATION forming part of Letters Patent No. 612,036, dated October 11, 1898.

Application tiled October 28,1897.

To all whom t may concern: Y

Be it known that I, BnNeT MAGNUs WIL- HELM HANSON, a citizen of Sweden, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification.

This invention relates to oil-cups, the object being to providea simple and inexpensive device of this character that is adapted when in its normal or retracted position positively to exclude dust and other foreign matter from a journal or other member to be lu bricated and which at the same time is capable of manipulation to permit the introduction of a lubricant.

The device consists, essentially, of a longitudinally-slidable thimble or shell having an oil-inlet in its wall, the upper end of said thimble being closed and said thimble being retractable in a socket or seat in a support or analogous member, in connection with which the device is employed, and the top of said thimble being iiush with said support.

The socket or seat which receives the shell preferably communicates with a journal or other part to be lubricated, so that when the shell is protracted the lubricant will be fed thereto to supply said journal. The socket or seat is of a depth to cause the oil-inlet in the shell to be covered or closed by the wall of the support when the tube or shell is retracted or closed, in which position it is preferably locked or held. l

In the drawings accompanying and forming part of this specication, Figures 1 and 2 are cross-sectional views of a support with my improved oil-cup thereon, shown, respec-V tively, in its retracted and protracted positions and also having a portion of its walll broken away. Fig. 3 is a side elevation of the cup detached, as seen from the left in Fig. 1. Fig. 4 is an opposite side elevation of the same. Figs. 5 and 6 are views corresponding, respectively, with Figs. 1 and 2, showing a modified form of the device. Figs. 7 and S are views corresponding, respectively, with Figs. 3 and 4 of the modiiied form of cup; and Fig. 9 is a perspective view of a casing or support forthe cup.

Similar characters designate like parts in all the iigures ofthe drawings.

The oil-cup (illustrated in Figs. 1 to 4, inclusive) is designated by C; and it consists Serial No. 656,694. (No model.)

of a thimble or shell, which may be of cylinclosed by the head or cap 2, whose periphery may be milled or roughened to permit of its ready manipulation. The wall or body of the shell C is punctured ata convenient point to form the inlet or port 4, adapted to receive a lubricant for application to a journal.

The shell or thimble C is fitted in a correspondingly-shaped socket or seat 5, formed in a support, as S, which in the present case represents the crank-hanger of a cycle, although it is apparent that the device may be put toother uses.

The support S surrounds the vjournal portion of the crank-shaft 6, fragments only of these parts being shown.

The socket or seat 5 communicates with the shaft 6 through the channel 7, so that the lubricant will pass from said socket to the shaft. Said socket is somewhat deeper than the shell C, so that when the latter is retracted or closed, as represented in Fig. 1, the wall of thesupport is adapted to cover the oil-inlet 4, thereby positively barring the entrance of dirt to the shaft 6.

The shell C is preferably thrown to its open position by the action of a spring, as 9, when it is unlockedfrom its support, and this spring is preferably` of the coiled type, although other forms may be employed, its upper end acting against the head 2 of the shell C and its lower end against the floor Sof the socket 5.

Means are provided for locking the shell C in its retracted or closed position, (indicated in Fig. 1,) such means consisting in the present case of a bayonet-joint. The locking-pin is designated by 10, and it is driven through an opening inthe support S, so as to extend into the irregular slot 12, formed in the body or'shank of the shelll C, said slot being of T shape, as indicated'in Fig. 4.

In Fig. l the shell C is indicated in its retracted or closed position, the coiled spring 9 being held under compression thereby and the locking-pin 10 abutting against the lower wall of the transverse or horizontal portion 13 of the slot 12, thereby holding said shell so that the wall of the support .S will cover the inlet 4.

Vhen it is desired to introduce a lubricant to the shaft 6, the milled head 2 is grasped and the shell is turned until the pin 10 is in line with or opposite the longitudinal or verdrical form and the upper end of which is tical portion of the slot 12, at which time the shell will be shot out of its seat by the spring 0 until the opening 4- is uncovered. XVhen the shell C has reached the limit of its out- Ward movement, the lower Wall of the slot 12 will strike the pin 10, and when the opening 4 is uncovered the nozzle of an oil-can may be inserted therein and the proper quantity of lubricant fed to the shaft' To assemble the parts, the spring 9 and the shell C will be successively placed in the socket 5, the slot 12 receiving the pin 10. At this time the shell can be pressed or forced into its seat until the pin 10 is in line with the T-shaped slot 12, when said shell can be turned either to the right or lett to prevent its Withdrawal.

The form of device which I have just described is particularly adapt-ed for use in connection with cycles, Where it is essential that particles of foreign mattershould be excluded from the bearings.

In Figs. 5 to S I have illustrated a modiied form of the device which is equally efficacious for the purpose intended, although it is applicable, preferably, to a different form of machine or apparatus, such as a planing or milling machine, a portion of the bed of which is designated by B. The modified device is so constructed that when retracted its upper edge or head will not project above the bed B, but will lie flush or in a common plane with said bed, as indicated in Fig. 5, thereby oilering no obstruction to a traveling carriage or table mounted on the upper surface of the bed. The part to be lubricated is designated by 15, it communicating by the passage 1G with the socket or seat 17 in the bed or other supporting structure B.

The oil-cup or shell is designated by C, it having the inlet 18 in its body, the coiled spring 19 acting against the closed upper end or head 2O of the shell C (see Figs. 5 and 6) and against the floor of the socket 17. The shell C' is supported for longitudinal sliding movement in the tube or sleeve 21, which is in threaded engagement with, or may be otherwise secured in, the part B, the upper edge of the sleeve being in alinement With the upper surface of said part B, as is also the upper edge oi' the shell Cl", so as to citer no impediment to the passage of a carriage upon the bed B. The shell C is equipped with the projecting pin 22, adapted to ride or travel in the slot 23m the sleeve 21 when the part C is thrown to the position shown in Fig. G.

To lock the shell C in its closed position, it is pressed into the sleeve 21 until the pin 22 is in line with the under side or solid portion of said sleeve, at which time the upper face of the shell is flush with the part B, the shell C then being slightly turned to lock the same closed. rlhe head 2O has the slot 23 to receive a suitable instrument by which the shell C' can be turned into or out of its seat, as occasion demands. The encircling sleeve 21 has the notches 21 in its upper edge to reeeive a spanner or other instrument by Which it can be driven into place or removed.

lIaving described my invention, I claim- 1. In a lubricator, the combination, with a fixed support having a socket, of a thimble having an oil-receiving inlet in its wall, and having its upper end closed, said thimble being reciprocatory in two directions in the socket, and the wall of the socket covering the inlet when the thimble is retracted; a protractile spring acting against the closed end of the thimble; and means for limiting the longitudinal and lateral movements ofthe thimble.

2. In a lubricator, the combination, with a support having a socket, of a sleeve located in, and shallower than, the socket, said sleeve having a slot, and a thimble in the sleeve and provided with a pin located when said thimble is retracted under the solid portion of the sleeve, said thimble having an inlet that is covered by the sleeve when the thimble is retracted.

3. In a lubricator the combination, With a Y support having a socket, of a sleeve removably itted in the socket and having a slot in its Wall extending to its lower edge; a thimble having an oil-inlet in its side and provided with a pin located When the thimble is in its normal position under the solid portion of the sleeve and adapted when said thimble is retracted to enter the slot; said inlet being covered by the sleeve when the former is in its retracted position, and a protractile spring acting against the thimble.

4. The combination, with a support having a socket, of a thimble having an opening in its Wall and its upper end closed, said thimble being slidable in said socket, and its upper edge being substantially iiush with the upper surface of said support, and the latter being adapted to cover the inlet when said thimble is in its retracted position; a spring acting against the thimble and tending to force the same from its socket, thereby to uncover said inlet; and means for locking the thimble in its retracted position, and the thimble being tu rnable in its socket to release the same from the action of said locking means.
